In Schafer and Strimmer (and other papers) they also discuss variance shrinkage and then they tend to combine both shrinkage of the sample covariance with shrinkage of the variance (e.g. in corpcor). …

For gene ranking (for GSEA, for example) and visualizations (on volcano plots, for example), DESeq author Michael Love suggests shrinking of the effect sizes (log-fold changes) with the `lfcShrink` fu…

shrinking the endog is another principle that allows reuse of existing methods for robust regression. This is similar to winsorizing and an alternative to trimming or dropping outliers (e.g. #3273 #9…

(mainly parking a reference for an old idea)
variance and covariance estimates are not very good in small or very small samples.
One idea is to use penalized or shrinkage (co)variance to get bette…
